breaking news tonight in the fantasy sports industry. the two largest websites draft kings and fan duel defending their integrity of their sites. according to "the new york times," a draft kings employee accused of win mortgage than 300 thousand dollars on fan duel in a move similar to insider trading. you know, people have been playing fantasy sports for years. now it's daily and weekly. as we learn more about the scandal, the debate is heating

up over whether fantasy sports is considered gambling. in most of the country, the answer is no. step up to the plate at draft kings.com. the ads seem to be everywhere. the target audience young men who know their sports or like to think they do. so much so they're willing to place a wager on stats or how an individual player performance. on your cell phone, you can play any time, any place. >> it opens up a whole another app and you can never escape it. >> reporter: the two biggest daily fantasy contests are draft kings and fan duel. >> i like it a little better than traditional baseball because it gives you a chance to reset and do something new every week. >> reporter: this sophomore plays on his cell phone. >> last year i spent more than i wanted to. so i set myself a limit of no more than $20 for the season. i usually play in the dollar leagues. >> reporter: jeron henderson wants to try. >> i'm interested in a couple million dollars or 100, 200,

300, anything to help out my pockets. >> reporter: so is it a game of skill or chance? the websites contend it's all about skill. so it shouldn't be considered gambling. but critics argue that doesn't matter. chance would make it gambling. skill means it takes talent, a deep understanding of the sport and rosters. even with an assist from those spreadsheets filled with stats. the websites argue it's like the stock market. those who participate do their homework. but some who study gambling addicts say there is potential for it to lead to an unhealthy addiction. >> and it certainly meets our clinical definition of gambling, which is wagers or risking something of value on an event whose outcome is certain. there are many forms of gambling that takes skill. people bet on golf. people have tried to define poker playing as a game of skill rather than gambling.

so even skilled games, there is an element of uncertainty. >> reporter: so far 45 states have declared the websites and their contests legal. courts and congress have yet to weigh. in we reached out to the fantasy sports trade association. they tell us there is no reason to call these websites gambling. it's unfortunate that the maryland center for excellence in problem gaming would unfairly characterize the fantasy sports industry in a manner that is not supported by the facts or the law. today's fantasy sports contest represent the natural evolution of a skill-based competition that fans have enjoyed for decades. >> i'm worried about it a little bit. but i feel like we're not putting too much out there. but you have so much more to gain. >> i guess in a way it is gambling. but i would hesitate to call it like traditional gambling or legally gambling. i think there is a lot of things online you can put your money towards, games of chance or skill, whatever you want to call it. >> you know, we talked to a lot of young men in our area for this story. but stats show women use the

sites too. about one in three users are women. you can learn a lot more about how much money people are spending in fantasy sports online and the people using these sites. it's all on nbcwashington.com. doreen? here is a story you may want the hear before you go to bed. general mills is recalling 1.8 million boxes of cheerios and honey nut cheerios cereal. some of the boxes labeled gluten-free could actually contain wheat. they say wheat flour was accidentally introduced to the system in an isolated incident. the recall affects honey nut cheerios with better if used with dates of july 12, 2016 through july 25, '16 as well as original box dates july 14 through july 17 of next year. speaking of breakfast, mcmuffin lovers, tomorrow is your day. you can have your favorite breakfast sandwich for all three

winds out of the north now at 3 miles per hour. and take a look at the temperatures. already in the 40s. 47 in warrenton. 48 right now in gaithersburg. 51 in baltimore. fort immediate right now coming in at 46 degrees. so yeah, it's chilly. it's going to be a lot cooler by early tomorrow morning. we're not going to see any rain most of this week there is only one exception to that. i'll get to that in just a second. right now satellite radar showing clear skies around our area. but notice just out of the south, the clouds moving in towards portions of the delmarva, across portions of south carolina, north carolina. look at this monster storm here. this is the storm that really helped to create all that flooding into the carolinas. it's finally moving off the coast. so it's taking the bulk of the rain just offshore now. but there is more forming in north carolina and south carolina. so they are not out of the woods just yet. this storm moving off slowly, right behind joaquin there is hurricane joaquin making its way to the north of bermuda. but they're all moving out and they'll continue to move away from the area. morning temperatures tomorrow

under mostly clear skies. 44 in gaithersburg. 42 in martinsburg. 47 in la plata. you're going to step out the front door tomorrow. make sure the kids have the jacket on. you'll probably need it too. here is the best news. with this kind of an atmosphere, we warm up quickly with sunshine. and we will see that tomorrow. 56 degrees by 8:00. 69 by noon. a great day to get lunch outdoors. 4:00, 76 degrees. looking pretty good. and then we cool quickly once again. the sun goes back down to 71 degrees. that impact forecast for tomorrow, well, weather is going to be a very low impact on your day. sunshine, chilly morning. but again, not bad at all. and that's going to be the case for the next four days in a row. 76 tomorrow. 79 on your wednesday. 75 on thursday. and look at the 80-degree day that of course is friday. why is it so warm? well, we've got a frontal boundary coming through. that cold front will sweep through late friday into saturday. saturday's high temperature only around 68 degrees. and there will be a chance for showers late friday into saturday. it's not going to rain most of

saturday. but it will be late friday. it could if you're thinking about heading out. maybe you've got date night friday night. it could be on the wet side. that's something we'll continue to watch. it does get cool behind that front. high temperatures in the 60s on saturday. saturday a cool day, but not a washout. don't worry about that threat of rain. it most likely comes early in the day. >> feels like fall. coming up, nats say so long to matt williams. to matt williams. could they be saying hello to a

>> no more matt williams. a lot of people saw this come, jason. >> still kind of crazy to think about. last year matt williams was voted the best manager in baseball. now he is without a job. the nationals, they had a roster certainly capable of playing october baseball. but everything that could have gone wrong turned out horrible for matt williams. from the injuries to players underperforming, and even not getting along in the dugout. either way you look at it, williams never stood a chance of returning for next season. today general manager mike rizzo spoke to the media by phone about the firing of williams and his entire staff. >> there nobody more disappointed about the 2015 season than i am. we thought that we put together a roster that should compete for not only the division title, but to move along throughout the play-offs. it didn't happen for a litany of reasons. we take pride in the organization that we have and the process that we use to make the decisions here in washington. >> so who may be on rizzo's radar for this next hire? the name everyone is talking about, cal ripken jr.

news sports reached out to cal ripken's camp. he had no comment at this time. keep in mind he has no managerial experience. >> that is key. >> rizzo and the nats, if they're looking for experience, this guy, bud black could be your man. he spent nine seasons with the san diego padres. he was fired this year back in june. and finally, rizzo made a point not to rule out nationals bench coach randy knorr. he has been with the organization since they were in montreal. moving on to the redskins now. four weeks into the season, and it's not over for the skins yet. this 2-2 start might have been the best case scenario anyone could have asked for before the year started. but people within the organization, they're not satisfied with this .500 record. jay gruden is expect mortgage from his football team. >> i like the fact that we're competing. i like the fact that our guys are giving great effort. and i think the way they're preparing, it's going to pay dividends for news the long run. being 2-2, it's not 4-0, but

we're tied for first in division. after the first quarter. we're happy about that. >> so the redskins won the game, but another injury came along with that victory. this time it's tight end jordan reed. reed sprained his mcl and his ankle yesterday. he also suffered a concussion in the game. the former third round pick has missed 12 games the last two seasons due to injury. this would be his fourth diagnosed concussion since his college days. earlier today, some very special guests at redskins park. 31 women in the middle of their cancer treatment were pampered by some of their favorite players. this all part of the eighth annual all star survivors breast cancer celebration spearheaded by cancer survivor tanya snyder, the wife of redskins owner dan snyder. it's not just about the women getting excited here, because the players, they were pretty thrilled to be there too. >> it means a lot just to give back and these ladies are going through a lot. i can only imagine. but just to get them to take their minds for a few seconds, just to enjoy.

some of the players, and kind of just love on them. i think it means the world to them. them. >> that's a great event by the

but he is going to wait to look at the poll numbers before he makes any more pumpkin paintings. he also says he is going to paint on foam pumpkins from now on so the artwork lasts longer. just think what trump is going to look like in a few weeks when he starts to get moldy. >> the hair
